Cannot open load file" "No such file or directory" "tex-buf

[nameiwillforget]

I haven't written any Latex in a few weeks and only now noticed that I cannot eval

(use-package latex-extra)

anymore because I get

Debugger entered--Lisp error: (file-missing "Cannot open load file" "No such file or directory" "tex-buf")

I'm guessing this is related to this: https://github.com/Malabarba/latex-extra/issues/35

Auctex version is 14.0.3, Emacs is 30.0.5.

I take it the problem is that AUCTeX is now on version 14, so latex-extra is still require-ing tex-buf, which it was supposed not to since this commit. There's a pending pull request to address this problem.

In the meantime, if you replace these lines in latex-extra:

(unless (string-prefix-p "13" AUCTeX-version)
  (require 'tex-buf))

with this:

(when (version< AUCTeX-version "13")
  (require 'tex-buf))

I think you should be good to go for now.
